Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with type 2 diabetes mellitus and chronic kidney disease is referred to a registered dietitian for a comprehensive nutrition assessment and individualized medical nutrition therapy as part of the MIPS nutrition/dietician specialty set (G4017). The patient arrives at an outpatient outpatient clinic affiliated with a multispecialty medical group for a 60-minute visit. The clinical workflow begins with the dietitian reviewing the referring clinician’s notes, current medications, recent lab results (HbA1c, serum creatinine, potassium), and weight trends. The dietitian conducts a focused nutrition-focused physical assessment, documents dietary intake and barriers, performs nutrition diagnosis and goal setting, provides tailored nutrition education and an initial meal plan, and documents measurable outcomes and follow-up frequency. A care plan and progress notes are placed in the electronic health record for the referring physician and interdisciplinary team. Typical sites of service include outpatient clinics, hospital outpatient departments, and physician office-based dietitian services participating in value-based reporting (MIPS).
